Anybody calling Dragon Quest's inclusion in Smash as a shill pick has entirely missed the point of why Dragon Quest would be included in Smash. You're choosing a super reputable series with a 30 year history to include in Smash that had a massive hand in influencing the genre of JRPGs as a whole. Calling Erdrick a shill pick is the equivalent to calling Ryu a shill pick. Just because the character isn't a massive fan favorite doesn't make them shill picks. There's a genuinely compelling reason to add Dragon Quest to Smash in of just representing that legacy alone. Yes, maybe they do want to market it more in the States, but it's most definitely not a shill pick for Japan and unless they very clearly state that the only reason that they included a Dragon Quest character was to try to make the series sell better in the West, then he's not a shill pick.
To build somewhat on that, I'm still always confused by the fact that the community seems to demand that characters also be popular in the West. The previous frames of reference for Sakurai talking about not including Japanese characters were the likes of Marth and Roy almost being cut from Melee, Lucas's situation in Brawl with no Mother 3, and Takumaru. All three of them suffered from literally never having been released in the West, whereas Dragon Quest has consistently been released in the West outside of the SNES era and hasn't missed really any titles in recent memory with regards to releases in the West. The series isn't some unknown entity that people will just be bewildered to see all of a sudden. No one has ever provided me with a convincing reason as to why Japan's biggest third party franchise not currently in Smash (Resident Evil is sort of there, but falls short in merch and cultural relevance) can't just be a pick for Japan.
Not all Smash picks need to have the absolute most worldwide appeal or need to pander to the West so damn much. Nintendo really wants to sell the Fighter's Pass, and if you've bought it, well they've made their money and don't really care if they sell you one character you may be less keen on. You're also essentially getting a Challenger Pack for Free with the Fighter's Pass, so they can also more or less afford a mulligan to sell to customers if they want to. I think Dragon Quest would be a pick decided upon to appeal to Japanese fans and I wish the Smash forums were more willing to see that (And yes, in our horribly limited and narrow Japanese polls, Dragon Quest hasn't become super popular in Smash, but again, there are other reasons to pick characters than their immediately recognizable popularity specifically in Smash).
Also, just as a note, for all of those people speaking about the people who use Erdrick and Steve to deny Smash fans other things, I feel like you need to learn to ignore GameFAQs and 4chan. Of course you're going to find ****ty people trying to be pompous know-it-alls on those places. I've seen very little of that here on SmashBoards or even on Reddit for example. Certain corners of the internet are more deserving of your time and effort than others, and those places aren't it.
